When does the PSTN Switch-off Start?
It’s already started. As of the 5th September 2023, BT Openreach initiated the first phase of the PSTN Switch-off with the national stop-sell of the Public Switched Telephone Network (PSTN). This means that BT Openreach are no longer offering new PSTN-based services. It’s important to understand that you can continue using pre-existing legacy PSTN services until the complete Switch-off in 2025. However, during this period, you will not be able to purchase any new services or modify any existing services that rely on ISDN or PSTN.
When is the final PSTN Switch-off happening?
BT Openreach has announced it intends to Switch-off the traditional analogue telephone network in December 2025.
Why is the PSTN Switch-off happening?
As PSTN has formed the infrastructure for UK telecommunications the 1800s, unsurprisingly it has become antiquated and costly to maintain. BT Openreach are switching off the PSTN and ISDN network to pave the way for a fully digital network which can meet the demands of the new digital era.
